Very specialised interests are, however, a less satisfactory source of happiness than a general zest for life, since they can hardly fill the whole of a man’s time, and there is always the danger that he may come to know all there is to know about the particular matter that has become his hobby.

Context

“It is quite impossible to guess in advance what will interest a man, but most men are capable of a keen interest in something or other, and when once such an interest has been aroused their life becomes free from tedium. Very specialised interests are, however, a less satisfactory source of happiness than a general zest for life, since they can hardly fill the whole of a man’s time, and there is always the danger that he may come to know all there is to know about the particular matter that has become his hobby. It will be remembered that among our different types at the banquet we included the gormandiser, whom we were not prepared to praise. The reader may think that the man with zest whom we have been praising does not differ in any definable way from the gormandiser.” source
